Description
Technical field
The present invention relates to transmission format judging method.Say more definitely, the present invention relates in the communication mode of 3rdGeneration Partnership Project (3GPP) defined, according to attached to sending the TFCI that encode by ReadMuller (Transport Format Combination Indicator) that sends on the data, the transmission format judging method that the transformat of transmission data is judged.
Prior art
In 3GPP regulation communication mode, stipulated that in order to satisfy various requirements in the communication, making various services are communicated becomes possibility, the communication speed maximum can correspond to the style of 2Mbps.
Exist voice and such continuous data and even the high-speed packet of animation as service, it is characterized in that the channel (physical channel) of multiplexing a plurality of service on one or more physical layer transmits.
In 3GPP regulation communication mode, in order to carry out the communication of aforesaid several data, the 3rd layer of message, to the unified suggestion of the set (Transport FormatCombination Set-TFCS) of combinations of transport formats, at the MAC of the 2nd layer the sublevel that belongs to transmit leg (Medium Access Control) layer, according to transmitting flow, selection will transmit according to the combination (Transport Format Combination TFC) of wherein which kind of transformat, and attached to transmitting the indicating device (TransportFormat Combination Indicator-TFCI) that sends the expression combinations of transport formats on the data.
And, the 2nd layer according to selected transformat, carry out error correction coding and and the coupling of physical channel to transmitting data itself.The recipient, in order to carry out handling to the format conversion/error correction decoding of the channel that is used to transmit from physical channel, as identification is the method that the combination (TFC) according to which kind of transformat transmits, and needs discern its form according to the TFCI that send attached to data upload.According to this TFCI, with reference to the set (TFCS) of above-mentioned combinations of transport formats, the combination (TFC) of identification transformat is carried out handling to the format conversion/error correction decoding of the channel that is used to transmit (transport channel) from physical channel.
Because this communication is radio communication, therefore need to consider to transmit the environment condition of severe here.Stipulate that in 3GPP regulation communication mode actual transmission data will be used the Turbo code of encoding rate 1/3 or the convolution code of encoding rate 1/2 or 1/3, carry out the error correction protection.
And,, use (32,10) sub-code of second order Reed-Muller code or (16,5) bi-orthogonal code (first order Reed-Muller code) to also stipulating attached to the TFCI that sends on the data.Compare with this Turbo code or convolution code, the Reed-Muller sign indicating number to correct ability lower.
But, as top said,, all to carry out to the format conversion of a plurality of transport channel or error correction decoding processing of carrying out thereafter etc. from physical channel according to the error correction decoding result of TFCI.In other words, if having mistake in the detection of TFCI, can't carry out the error correction decoding of data itself.Therefore, the error property of TFCI will become bottleneck, become the result of the whole receiving feature of decision.
The number of the transformat of each transport channel is difference with the difference of transport channel kind.For example, the transformat that ISDN or AV etc. is sent continuously the transport channel that (circuit switching system) data distribute has 2 classes, and promptly in fact only may have regular length is the long and non-existent situation of BLOCK.And, in this case,, on radiolink, be stopped up to this channel in case data begin to send, in fact data all can not be interrupted.
And the processing unit of TFC decision is different with the unit of transfer of TFCI sometimes.The unit of transfer of TFCI is 1 radio frames unit (unit of transfer on the physical channel), and the TFC decision is 2 radio frames units sometimes, is more than the 2 radio frames units sometimes.Under the sort of situation, sometimes identical TFCI can be transmitted 2 times.
And though each transport channel all has transformat, each transport channel is handled the unit difference sometimes.For example, suppose to have two transport channel, the processing unit of a transport channel A is 2 radio frames units, and another transport channel B is 4 radio frames units, the transformat of transport channel A can change to 2 radio frames units so, and the transformat of transport channel B can change to 4 radio frames units.Because TFCI is the minimum treat unit's change according to each transport channel, therefore TFCI can change according to 2 radio frames units in this case.
Summary of the invention
Therefore, main purpose of the present invention is change cycle etc. of the transformat of the processing unit of the characteristic that is considered as the data of circuit switching system data itself, each transport channel and each transport channel, provides the transmission format judging method of usefulness.
The present invention is a kind of transmission format judging method, comprising:
The 1st step receives data and represents the identification code of its transformat; The 2nd step is decoded to the identification code that receives; The 3rd step is judged the appropriate property of decoded result in the 2nd step; The 4th step, the kind of the data that judgement receives; The 5th step, when judging decoded result when not having appropriate property, according to the kind that determines in the 4th step, the judgement transformat.
Better is, transformat comprises expression the 1st class form of data content and the 2nd class form that expression does not have data content, when the kind that is determined in the 4th step is judged as circuit switched or continuity data, be judged to be the 1st class form in the 5th step.
Other situations of the present invention are a kind of transmission format judging methods, comprising: the 1st step receives data of sending by each frame in 1 delivery time and the identification code of representing its transformat; The 2nd step is judged the identification code decoding that whether has by other frame that receives in 1 delivery time, its decoded result is judged as definite transformat of appropriate property; The 3rd step when when the 2nd step has determined definite transformat, judges that the transformat of the data in this frame determines that with this transformat is identical.
Better is also to carry out: carry out the identification code in this frame decoding, judge its decoded result appropriate property the 4th step and be judged as when not having appropriate property the judgement of the 3rd step at the 4th step decoded result.
Other situations of the present invention are a kind of transmission format judging methods, comprising: the 1st step receives data of sending by each frame in the delivery time and the identification code of representing its transformat; The 2nd step is decoded the identification code in this frame to each frame; The 3rd step according to the property of having a mind to of the decoded result of each frame in the 2nd step and each decoded result, is judged definite transformat that 1 delivery time is interior.

Fig. 3 is the flow chart that is used to illustrate the action of one embodiment of the invention, Fig. 4 is the flow chart of the appropriate property of the example decoded result of judging TFCI shown in Figure 3, Fig. 5 A～Fig. 5 C is expression, the table of the set of the combination of the object lesson of the set of the transformat of certain two channel and its transformat of example expression.Fig. 6 is expression, example based on Fig. 5, on the transport channel of each time, see, the figure that represents the transmission example of each transport channel and TFCI, Fig. 7 A～Fig. 7 D are, in the example shown in Fig. 5 A～Fig. 5 C, when to transport channel #1 allocation packets switching system data, when transport channel #2 has distributed the circuit switching system data, on the transport channel level of each time, see the transmission example of each transport channel and TFCI.
With reference to Fig. 1～Fig. 7, embodiments of the invention is elaborated.
A plurality of transport channel transmission that is re-used on physical channel.As an example, consider the example shown in Fig. 5 A～Fig. 5 C.In this case, transport channel has two, supposes to exist transport channel #1 and transport channel #2.And all there is delivery time interval (processing unit) in each transport channel, and the processing unit of supposing transport channel #1 is 20msec, and the processing unit of transport channel #2 is 40msec.
Each transport channel is stipulated each transformat at interval delivery time, and the transformat of transport channel #1 shown in Fig. 5 A, supposes it is 320bit * 0,320bit * 1,320bit * 2,4 kinds of 320bit * 3.
And the transformat of transport channel #2 shown in Fig. 5 B, supposes it is 120bit * 0,2 kinds of 120bit * 1.Because these two transport channel will be sent by multiple week, so will have combination in the transformat of transport channel.Combination (TFC) and this set (TFCS) of this transformat are expressed as Fig. 5 C.
And, the identification code of this TFC of expression is called TFCI.Promptly, if TFCI is 0, the transformat of transport channel #1 is TF0 (320bit * 0), the transformat of transport channel #2 is the combination of TF0 (120bit * 0), TFCI is 5 words, the transformat that will become expression transport channel #1 is TF1 (320bit * 1), and the transformat of transport channel #2 is the combination of TF1 (120bit * 1).
Data and TFCI send together, the recipient, with reference to TFCS (table of Fig. 5 C), determine the transformat of each transport channel of these minimum data that send unit according to the TFCI that receives, carry out from the physical channel of data format conversion, and error correction decoding is handled to a plurality of transport channel.Below, the decision of the transformat in embodiment of the invention processing method is described.
SP1 step shown in Figure 3 (abbreviating SP in the diagram as), judge whether the decoded result of TFCI is appropriate.That is,, whether wrongly therefore to judge in the value as error correction decoding result output because TFCI is not carried out error detection coding.Embodiment as this judgement represents flow chart at Fig. 4.In SP21 step shown in Figure 4, TFCI also exports the likelihood information about correspondence decoding result reliability in decoding.
In the SP22 step, judge in TFCS, whether there is decoded TFCI.If there is not decoded TFCI among the TFCS, in the SP23 step, the decoded result of TFCI will be judged as imappropriate.If there is TFCI among the TFCS, will judge in the SP24 step, whether the reliability of the soft decision symbol of the TFCI of coding back (before the decoding) is also bigger than certain threshold value.Here said certain threshold value is meant the value that is fixed as certain level.If reliability is also littler than certain threshold value, so in the SP25 step, decoded TFCI will be judged as imappropriate.
If it is reliability is also bigger than certain threshold value,, that whether judgement is also bigger than certain threshold value about the likelihood information of the reliability of corresponding decoded result in the SP26 step.About the information of the reliability of corresponding this decoded result, will when being carried out decoding processing, export TFCI.If likelihood information is also littler than certain threshold value, so will be in the SP27 step, decoded TFCI will be judged as imappropriate, if also bigger than threshold value, so in the SP28 step, decoded TFCI will be judged as appropriate.
So, appropriate if TFCI is judged as, in the SP2 of Fig. 3 step, 1 of definite each transport channel is handled unit with interior transformat.But,, decide according to the result who determines for the first time for the transformat of the transport channel of having determined.
But,, judge handle within the unit 1 of transport channel, whether transformat is determined when in the decoded result that determines TFCI when wrong in the SP3 step.Here handle unit and be meant foregoing 20msec (transport channel #1), or 40msec (transport channel #2) for 1.Though TFCI transmits by 10msec, if but 1 processing unit is 20msec, identical TFCI will be transmitted 2 times, if the TFCI at the 1st time has just determined transformat, in the SP4 step, even the TFCI of current decoding does not have credibility, also to follow the transformat of having determined.
In SP3 step shown in Figure 3, determine transformat in the unit when determining when handling at 1, in the SP5 step, data in certain transport channel that is receiving are distributed in judgement, whether be the continuity data, whether be the circuit switching system data promptly.If not the circuit switching system data,, when transformat is maximum,,,, guarantee the memory area that it is necessary as TF1 if TF3 is Fig. 5 B for example if Fig. 5 is A in the SP6 step.If the circuit switching system data, after the SP7 step begins to receive, judge whether have the transformat that received for 1 time beyond the TF0 in the past at least, promptly judge the TFCI that whether received data.After radiolink is opened, after promptly radio communication control part 5 is opened radiolink, send data, therefore when the communication beginning, the time that occurs not having data to exist is with from application layer.This processing is a measure that is used for the interval that corresponding not these data exist.
If (120 * 0 or 320 * 0bit) in addition transformats will be thought the transformat that does not have data to exist in the SP8 step not receive TF0.If received the transformat beyond the TF0, whether be voice in SP9 step decision data, if not voice, will be considered to have the transformat of data existence in the SP11 step.Because circuit switching system and be that data beyond the voice belong to the continuity data, therefore in fact only have and two kinds of situations of this transformat not.For example, the such situation of the transport channel #2 shown in the image pattern 5B.If being determined to is voice, will think the transformat of maximum rate in the SP10 step.
Though voice etc. are the data of circuit switched, there are a plurality of transformats such as tone-off, background noise, speech data.In this case, if stand on user's the position, it is not so important that tone-off or background noise are compared with actual speech data.
And, to the data of tone-off or background noise,, when error detection, also will fail even carried out wrong conversion/signal processing as speech data, press tone-off in voice CODEC portion and handle.Therefore, that is to say that it is the most useful handling as the data of voice itself.
And flow chart shown in Figure 3 is according to 1 unlimited frame unit (supposing it is 10msec), promptly repeats according to the unit that transmits TFCI.
Below, reference transmission example shown in Figure 6 is further done and is specified.Fig. 6 is according to 1 unit on the physical channel (1 radio frames 10msec), and is multiplexing and send two transport channel in the example of Fig. 5 A and Fig. 5 B, and the example of migration takes place its transformat.
Because the delivery time of the transport channel #1 shown in Fig. 5 A interval (processing unit) is 20msec, therefore transformat is identical when 2 radio frames units.And similarly, because the delivery time of transport channel #2 is 40msec at interval, transformat is identical when 4 radio frames units.And in the nature of things, TFCI will be according to (being 20msec in such cases) variation at interval of minimum delivery time of multiplexing transport channel.
Also have, what Fig. 7 A and Fig. 7 B represented is that the data of transport channel #1 are packet switching system data, the example the when data of transport channel #2 are continuity data (ISDN or AV).What Fig. 7 C and Fig. 7 D represented is the example the when data of transport channel #1 and transport channel #2 all are the packet switching system data.
Fig. 7 A, though because the data of transport channel #2 are continuity data (ISDN or AV), become TFO midway, actual is an example that impossible exist.
Err has taken place at the 5th frame in Fig. 7 B.It is imappropriate that this represents that at Fig. 4 the decoded result of TFCI is judged as.At this moment, in Fig. 3, the transformat of transport channel #2, to be judged as imappropriate in the SP1 step, be not judged as in the SP3 step and determine, be judged as in the SP5 step and belong to the circuit switching system data, be judged as the data that received beyond the TF0 at SP7, be judged as in the SP9 step and be not voice, be judged as existence in the SP11 step.In this case, the transformat of transport channel #2 will be regarded as TF1.
In example in the past, if Err takes place TFCI, connect the conversion of data format, decoding processing itself all can't be carried out, but in the middle of this embodiment, can carry out suitable processing according to belonging to this characteristic of continuity data.
And, the transformat of transport channel #1, to be judged as imappropriate in the SP1 step, be not judged as not definite in the SP3 step, be judged as logicalnot circuit switching system data in the SP5 step, guarantee the maximum region of memory in the SP6 step, discarded data at that time replace with the data of reliability 0.This is handled, and is the processing that the TFCI of expectation next frame is correctly judged, for example, according to next TFCI, TF is judged as when correct, can expect that by error correction it will be correctly decoded together with the data of next frame.Particularly to handle unit be 40msec etc. long effectively.
Fig. 7 C is that the decoded result of TFCI is judged as improper example at that time the 7th radio frames.
At this moment, the transformat of transport channel #1, be judged as imappropriate in the SP1 step, be not judged as not definite in the SP3 step, be judged as logicalnot circuit switching system data in the SP5 step, owing to uncertain, therefore to guarantee the maximum region of memory in the SP6 step, judge according to next TFCI.On the other hand, the transformat of transport channel #2 is judged as imappropriately in the SP1 step, be judged as definitely in the SP3 step, handles being used as the TF1 that determines.
In view of the above, handling though can not carry out the transforms decode of data in example in the past, in the middle of these examples of implementation, is this certain characteristic according to TFCI 1 delivery time at interval, can carry out suitable processing.
In the example of Fig. 7 D, Err takes place at the 6th radio frames TFCI, transport channel #1 and transport channel #2 will handle according to the transformat of determining.
As above content, according to embodiments of the invention, even and the TFCI that sends together of data wrong, the characteristic of utilizing the characteristic that sends data, can not changing at 1 delivery time interval T FCI, even when failing correctly to detect TFCI, also can suitably handle data itself.And,, can represent to judge the method for the appropriate property of decoded result for the error correction decoding result who does not have error detection bit.
Utilizability on the industry
According to the present invention, utilize to send the characteristic of data, at 1 delivery time interval T FCI not Even the characteristic that can change when failing correctly to detect out TFCI, also can be carried out data itself Suitably process. And, for the error correction decoded result of not examining wrong bit, can represent to declare The method of the appropriate property of definite decoding result can apply to mobile phone machine etc. and carry out radio communication The terminal device.
